Which of the following is not typically categorized as a password cracker?

• A. John the Ripper
• B. Hydra
• C. RainbowCrack
• D. Nmap

Answer: (D)

Password-cracking tools are built to recover passwords by trying many possibilities or using precomputed tables to speed up the process. John the Ripper is a classic example that cracks password hashes by using dictionary and brute-force methods with various rules and hash formats. Hydra is designed to perform rapid online brute-force or dictionary attacks against a wide range of network authentication protocols to test credential strength. RainbowCrack uses rainbow tables—precomputed chains of hashes—to accelerate cracking of hash values, making large portions of the search feasible much faster than brute-forcing alone. Nmap, in contrast, is a network mapper used to discover hosts, services, and vulnerabilities across a network. It isn’t intended to crack passwords, though it can be extended with scripts to test credentials in some scenarios; its primary purpose remains reconnaissance, not password cracking. Therefore, Nmap is not typically categorized as a password cracker.
